First heard on MTV's "World of Jenks". Term created by the rapper Maino. It goes something like this: You meet a girl for the first time. Take her back to her home or hotel and “give her the penetration of life”

Man 1: I'm taking you out on the town tonight for the first time. I wanna see some First Night Gangsterism.

Man 2: What?

Man 1: You gotta meet a girl for the first time. Take her back to her home or hotel and give her the penetration of life.
